利用转移反应1 1 B(d ,p) 1 2 B和1 2 C(d ,p) 1 3C抽取1 2 B 1 1 B +n和1 3C 1 2 C +n重叠函数的核渐近归一化常数 ,计算了1 2 B和1 3C核中价中子密度分布的均方根半径及其在核外的几率 .实验结果表明 ,1 2 B的第二 (Jπ=2 - ) ,第三 (Jπ=1 - )激发态和1 3C的第一 (Jπ=1 2 +)激发态为中子晕态 ,而1 3C的第三 (Jπ=5 2 +)激发态是中子皮态 .考察了库仑势和角动量对晕形成的阻碍效应 .提出了均方根半径对于有效核子分离能的统一的标度定律
Asymptotically normalized nuclei of 1 2 B 1 1 B + n and 1 3C 1 2 C + n overlap functions using the shift reaction 1 1 B (d, p) 1 2 B and 1 2 C (d, p) The root mean square radius of the mid-price neutron density distribution of the 1 2 B and 1 3 C nuclei and its extra-nuclear probability were calculated.The experimental results show that the second (Jπ = 2 -) of 1 2 B, the third (Jπ = 1 -) excited states and 1 3C first (Jπ = 1 2 +) excited states are neutron halo while the third 3C Jπ = 5 2 + excited states are neutron skin states. The impeding effect of Coulomb potential and angular momentum on halo formation was investigated, and a uniform scaling law of rms radius for effective nuclear separation energy
